In April of this year, Israel's Defence Minister Ehud Barak staged a
visit to Bogota, where his activities included marketing Israeli drones
to the Colombian state.
According to a subsequent report in the Colombian newspaper El Espectador,
one of Barak's selling points was that the technical intelligence
provided by drones helps reduce the failure rate seen in operations in
which only human intelligence is relied upon.
Given the recent history
of drone operations in various parts of the world, it would seem that
there's not exactly an inverse relationship between use of said aircraft
and the incidence of failure, at least insofar as rampant slaughter of
civilians qualifies as failure.
Conveniently, however, the state of Israel has tended to look less
frowningly on certain types of civilian slaughter, converting the
practice into evidence of the "purity of arms" - a military code of
ethics upheld in projects ranging from the ethnic cleansing of Palestine
to the extermination of nearly 20,000 persons in Lebanon in 1982 to the
drone-assisted massacre at the United Nations compound in Qana in
1996.
